Petri dishes are also used for cell cultivation of isolated cells from eukaryotic organisms, such as in immunodiffusion studies, on solid agar or in a liquid medium. Penicillin, the first antibiotic, was discovered in 1929 when Alexander Fleming noticed that mold that had contaminated a bacterial culture in a Petri dish had killed the bacteria all around it. For example, if we talk about test tubes, then they are long and cylindrical. They can be sterilized by placing the petri dish in the autoclave. Before being used forculture purposes, it is important to ensure that the Petri dish is not onlyclean, but also sterile. [16], Some Petri dishes, especially plastic ones, usually feature rings and/or slots on their lids and bases so that they are less prone to sliding off one another when stacked.

It is often used metaphorically, e.g. An alkaline earth metal by nature, rubidium is placed in the alkaline metal on the periodic table devoted to elements. A Petri dish (alternatively known as a Petri plate or cell-culture dish) is a shallow transparent lidded dish that biologists use to hold growth medium in which cells can be cultured,[1][2] originally, cells of bacteria, fungi and small mosses. To do this, it is filled with a layer of nutrient medium, on which a culture of microorganisms is sown. Storing the Petri dishes in the refrigerator prevents the water inside the dishes from evaporating (bacteria need a moist environment to grow). It is most suited for organisms that thrive on a solid or semisolid surface. A petri dish is a shallow round dish which is used to grow culture of different organisms. Besides being much cheaper and convenient than separate dishes, the multiwell plate is also more amenable to automated handling and inspection. They are usually covered, or placed upside-down, to lessen the risk of contamination from airborne spores.
